Toxins and Atomic wieght question!

Dr. Vinograd, I hope this is a legitimate question! I read some where that all toxins have an Atomic wieght and that they are eliminated from the body accordingly!
I was wondering if there is a list or chart showing the most common toxins in the body and there rates of elimination, and if there is. made available for use as an aide in personal detoxification!
I have a very limited knowledge in chemistry or physics and wonder if you could enlighten us on this subject!
I have the "periodic tables of elements" in front of me but can not really put any of it into a sensible concept!
I would really appreciate any thing that you could do to help understand these toxins and their elimination! Thanks Grog
